To Set Up a Server Farm

Install the administration server. You can install the administration
server through Sun Java System Web Server 7.0 Update 1 Installer GUI or through the wadm CLI.

You can choose the Express
installation option, which will install an administration server
on port 8989. Alternatively, choose Custom Installation option
for setting your preferences. To install the administration server, choose
the option Install server as Administration Server in
the installer setup screen. You need to specify the SSL port but may or may
not specify a non SSL port.

Note –

If a non SSL port is specified, an administration node
is created in the administration server node and this need not be registered
with the administration server explicitly.

To install the administration node , choose Custom Installation and then Install server
as administration node. Specify a port for installation. You do
not have an option to select non SSL port as all communication between administration
server and administration node is through a secure channel. During the installation,
you will be asked if you need to register the node with the administration
server. If you choose not to register the node during installation, you can
use the wadm CLI to perform this action.

Note –

You cannot install administration nodes through express installation.

Register the Administration Node with the Administration Server

The administration nodes have to be registered to the administration
server for them to be part of the cluster or the server farm. The administration
nodes will not start up unless they are registered to an administration server.
For registering the administration node execute the following command through wadm CLI.

This port is the one specified during the administration server installation.
Host is the hostname of the node where the administration server is installed.

This action will register the node to the administration server.

Note –

A node can be registered only from the same node . You cannot
go to the CLI of the administration server and register any node. Also the
registration of node with the administration server can be done in SSL mode
only.
